Maleic acid (M)-glycerol (G) mixture (MG) treatment for woods have been developed for improvement of water resistance and durability of woods and particle boards. Characteristics of MG and the mechanical strength of MG-treated cellulose as a model of wood were investigated to clarify the effect of MG treatment. Formation of ester bond between M and G was found during the preparation of MG solution, resulting in production of polyesters with more than 1,000 of molecular weight. Double bonds in M were maintained after the reaction of MG with cellulose. Reaction temperature of MG with cellulose over 180 degrees C affected a decrease in the moisture content and the reinforcement of tensile strength of filter paper.
